Freshness in a snap! Oliso Vac-Snap bags are designed with heavy-duty multi-layer construction that, when used with the Oliso PRO smart vacuum sealer creates an airtight waterproof heat seal. Air & odors are locked out to keep your food fresh 5X longer, reduce food waste, prevent freezer burn and save you hundreds of dollars a year on groceries! Works great for microwaving, simmering and sous vide cooking. VAC-SNAP resealable zipper-top bags allow for easy access, work for liquid or dry food and keep food fresh in the refrigerator, freezer or pantry; pre-built bags mean no cutting, waste or mess. Once the bag has been vacuum sealed, simply open the resealable zipper-top to add or remove food, then close and reseal up to 10 times. Made from heavy-duty, BPA-free #7 recyclable material making them the perfect durable storage bag. Includes 14 medium sized, 1 quart bags.
